Hwaran Lee

Hi! I am an assistant professor in the Department of Artificial Intelligence and Computer Science Engineering at Sogang University, where I lead HAILO Lab – Human-centered AI and Language for All.
My research is committed to understanding humanity and society to further develop human-like and trustworthy Artificial Intelligence. Recent primary interests has been building trustworthy and safe Large Language Models (LLMs), with a focus on: (1) construction of safety datasets, benchmarks, and evaluation metrics; (2) controllable language generation; (3) LLM security, including adversarial attack and red-teaming; (4) safety alignment and learning methods.
I obtained my Ph.D. in Electrical Engineering at Korea Advanced Institute of Science and Technology (KAIST) in 2018, advised by Prof. Soo-Young Lee. In 2012, I obtained my B.S. in Mathematical Science at KAIST. Before joining Sogang University, I was a lead research scientist at NAVER AI Lab from 2021 to 2025, and a research scientist at SK T-Brain from 2018 to 2021.
